For a country that stood at the bottom of the pyramid in terms of telecom penetration a decade ago, 2008 was a watershed when India’s subscriber base topped 350 million users to make its network the second largest in the world after China, displacing the US. The significant achievement was made possible by the mobile telephony segment of communications, which was once thought to be a gizmo for the rich – what with a tariff of Rs.16.80 per call when the telecom revolution began in the country in the early 1990s. But with tariff falling to 40 paise a call and incoming calls becoming free, mobile telephony began to appeal to the masses.
